The insulation sleeve 21 is in a pressed state at this time.

As shown in FIG. 2, the cell part 1 comprises a lower electrode 15 which is permanently installed on its front end.

To improve the safety, the outside of the lower electrode 15 is sleeved with an insulation sleeve 20.

Specifically, the insulation sleeve 20 can be consisted of rubber, resin, silica gel and the like.

It is to be understood that the mode to fix the lower electrode 15 in the cigarette body part 2 is not defined specially. Specifically, the fixing mode in the present invention is as follows: the insulation sleeve 20 is clamped inside the cell part 1, and the lower electrode 15 is subsequently clamped inside the insulation sleeve 20 so as to fix the lower electrode 15 within the cell part 1.

The insulation sleeve 20 is in a pressed state at this time.

The connection mode between the cell part 1 and cigarette body part 2 has no specific limitation, which can be achieved by interference fit, pin connection, clamp fit, screw-thread fit and the like.

Preferably, the mode of screw-thread fit is employed in the present invention, so that a detachable structure is formed by the cell part 1 and the cigarette body part 2.

Its specific structure is as follows: the end of the cell part 1 is equipped with an external thread, and the first copper element 30 of the cigarette body part 2 is equipped with an inner thread simultaneously; in this way, the outer thread is screwed with the inner thread so as to achieve the connection of the cigarette body part 2 and cell part 1.

When the cell part 1 and the cigarette body part 2 are in the state of connection, the top electrode 14 and the lower electrode 15 contact with each other for ensuring the connection between the electrodes.

The electronic smoking device also comprises a sealing component 10 which is arranged between the cell part 1 and the cigarette body part 2. Herein, the cigarette body part 2 and the cell part 1 are sealed by the sealing component 10.

It is to be understood that the sealing between the cigarette body part 2 and the cell part 1 can be achieved by the following three ways. However, it is not limited to these ways.

Specifically, as shown in FIG. 2 and FIG. 3, the lower electrode 15 has a cavity 16 in a first implementation.

When the cell part 1 is connected with the cigarette body part 2, two ends of the sealing component 10 are respectively inserted into the through hole 17 and the cavity 16.

Since the sealing component 10 is inserted into the through hole 17 and the cavity 16, the sealing between the cell part 1 and the cigarette body part 2 can be achieved.

The connection mode of the sealing component 10 and the through hole 17 is interference fit at this time.

One end of the sealing component 10 is inserted into the cavity 16, and its other end presses against the end of the top electrode 14. Herein the sealing component can completely block an opening of the through hole 17, in which case the sealing of the cigarette body part 2 and the cell part 1 is achieved by such structure.

The following beneficial effects can be achieved using the seal structure described above.

On one hand, hot air in the cigarette body part 2 does not flow to the cell part 1 during smoking so as to prevent the cell with sensitivity to heat from damage. On the other hand, such structure can prevent the loss of heating heat in the cigarette body part 2 during smoking.

The cigarette holder 3 is installed on one end of the cigarette body part 2.

The cigarette holder 3 and the cigarette body part 2 are detachable with respect to each other.

The cigarette holder 3 is consisted of soft material. For example, it can be consisted by rubber, resin, silica gel and the like.
